This study proposes a solution to the problem of limited network sensor coverage caused by insufficient sample size of probe vehicles.A framework is developed that estimates link travel times using available data from neighbouring links.The proposed framework was validated using field data from Vancouver, BC.The travel time estimation accuracy was found comparable to the existing literature.To analyze the impact of the probessample size on the accuracy of the proposed methodology, a case study was undertaken using a VISSIM micro-simulation model of downtown Vancouver.The...

While motorized travel provides many benefits, it can also do serious harm in the form of road-related crashes. The problem could be addressed thorough several approaches with engineering initiatives being recognized as the most sustainable and cost effective. Still, the success of the engineering approaches in reducing crash occurrences hinges upon the existence of reliable statistical methods that can provide accurate estimates of safety. However, it was not until recently that advances in statistical modeling techniques have facilitated the fitting of more advanced models to accurately...
